"Raising Jack Russell Terrier puppies is our greatest pleasure ~ Breeding the Irish Connemara remains our greatest responsibility”

DNA Profiling

We breed for health and temperament first.  Our Jack Russell Terriers have completed the following screenings and clearances: Thyroid panels, Luxating Patellas, Blood Chemistry & Complete Panels run, B.A.E.R. (hearing test). Temperament tested and Comprehensive Personality Profiles done.  They have completed DNA screenings for 38+ known disease markers more recently discovered/mapped.  As more DNA testing becomes available, we will take full advantage and test our terriers.

As you can see, our terriers are screened for dozens of inherent, genetic disease markers.  These tests are able to tell us if our dogs have a condition, or may be a carrier of a condition. Again, as other DNA based disease testing becomes available, we will be testing our terriers and noting so here. We use several different genetic laboratories as not one lab is able to provide us with all of the testing.

Canine Profiling (Genotyping) is used to establish a secure, permanent ID of each individual dog.  All of our Connemara foundation terriers have had their DNA profiled and recorded. DNA profiles can be used to positively identify and link a pup or dog to their heritage - All our Connemara pups can be linked to the Connemara line.

Each Connemara Jack Russell puppy has a copy of their DNA profile on file with DNA World Pet Registry, and goes home with a collar tag to certify they have been profiled and a Certificate of Parentage issued. The DNA Proof of Parentage Test is used to make a familial match and certify a proper breeding has occurred. This is done by comparing the DNA of the puppy, Dam and Sire.
If a website says: “We Health Test”…and then you don’t see a page devoted to health testing, or OFA numbers assigned to the terriers, or more information with a LIST of tests like the list above - then ASK QUESTIONS AND FIND OUT WHAT THAT MEANS.
